Effect of F1-GG-AO (A), F2-KC-AO (B), F3-GG-BO (C), F4-KC-BO (D), F5-GG-B (E), and F6-KC-B (F) (1–1000 µg/mL) on the viability of L-929 cells by MTT assay. A negative control (non–treated cells) was conducted and considered 100% viability. Mean values were calculated from 3 independent results. The * denotes the significative difference from the negative control (p < 0.05). NS means “not significant”. In all formulations examined, the viability of cells is observed to decline as the concentration increases.
